Donald Trump Jr. is a Dad Again!

A rep for Donald Trump Jr. confirms to OK! that the son of real-estate mogul Donald Trump and his wife Vanessa have welcomed their second child, a boy, into the world earlier today.

"Donald J. Trump III was born earlier today," the rep tells OK!. "Mother and son are doing fine."

The pair, who married in November 2005, are already parents to baby girl Kai Madison Trump, who will turn 2 on May 12.

Before this latest pregnancy, Donald Jr. talked to OK! about his wife’s desire for a big family. "She wants five [kids]. I might try to negotiate for a little bit lower," he joked. "I figured I’d have some leverage after number one, but about two days after, she’s like ‘Okay, I could do that again.’"

Donald Jr., along with his sister Ivanka Trump, will both be seen on the new season of Celebrity Apprentice, which premieres at 9pm on March 1 on NBC.
